ET-MTI Technical Specifications

General Description

The ET-MTI (Mini Telematics Interface) outperforms traditional vehicle telematics interfaces by offering a powerful combination of GPS, cellular communications technology, 3-axis accelerometer, on-board memory and OBD II generic and enhanced vehicle communications.

This extremely compact design is powered thru the vehicle’s diagnostic port. The ET-MTI is easy to install, requires no external cabling and supports most 1996 and newer passenger vehicles.

Combine the ETI-MTI with a web application to provide such services as vehicle tracking, geofencing, alert notification, safety services, vehicle diagnostics, vehicle convenience functions such as remote door unlock, data logging and more.
